SLUBBER OR FLY-FRAME.

Specification of Letters Patent.

Patented Oct. 16, 1906.

To all whom, it may concern..-

Be it known that we, GEORGE E. BOUVIER and JOSEPH N. PROULX, citizens of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Slubbers or Fly-Frames, of which the following is a specification.

Our invention pertains to spinning, and more particularly to slubbers or fly-frames; and it has for its object to provide a positive and direct driving connection intermediate the compound on the main shaft and the bobbin-shafts for transmitting motion from the former to the latter and one which Will maintain a uniform speed during the traverse of the bobbin-rail and be unaffected by such traverse and Which is simple, is not liable to get out of order, and is susceptible of being quickly and easily repaired.

Other advantageous features peculiar to our invention will be fully understood from the following description and claims when the same are considered in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical section of so much of a slubber or fly-frame as is necessary to illustrate the preferred embodiment of our invention. Fig. 2 is a detail vertical section taken at a right angle to Fig. 1. Fig. 3 is a horizontal section with certain of the parts in plan. Fig. 4 is a detail vertical section showing the cam and the parts cooperating there with; and Fig. 5 is a detail horizontal section illustrating the vertical slide, the guideway therefor, the stub shaft and antifrictionroller carried by the slide, and the cam for acting against said roller.

Similar characters of reference designate corresponding parts in all of the views of the drawings.

The bobbin-rail A and bobbin-shafts B and C travel up and down, being guided by the rail D and deriving such movements from the usual racks and gears (not shown) operated by the lifting-shaft E, and the bobbins,(not shown) are rotated by the bobbin-shafts B and C through the medium of the usual gears, which We have deemed it unnecessary to illustrate.

One of the bobbin-shafts, preferably the shaft 0, is equipped with a sprocket-gear F, and this sprocket-gear is connected through a sprocket-belt G with a sprocket-gear H, which is mounted on the main shaft I and is carried by the hub J of the compound gears. (Not shown.) It will thus be seen that the bobbin-shafts B and C are driven directly from the compound through the medium of a simple and inexpensive connection and one that has no delicate parts such as are likely to get out of order after a short period of use.

It will also be observed that the driving connection is readily accessible, and hence may be repaired with facility when necessity demands.

It is essential to rotate the driven sprocket F at an even speed in order to avoid backlash and the production of an uneven twist to the yarn, and to this end We provide the regulator-sprocket gear K. This regulatorsprocket gear is arranged to turn on a stud L, carried by a vertically-movable slide M, disposed in a fixed guideway N, and it is moved up and down through the medium of a cam P, secured on the lifting-shaft E and acting against an antifriction-roller R, mounted on a stud or stud-shaft S, also carried by the slide M. The lifting-shaft E is of the type common to slubbers i. 6., is turned first in one direction and then in the other by the ordinary means, which forms no part of my invention and which I have deemed it unnecessary to illustrate. The regulatorsprocket gear K engages the driving-stretch, preferably the upper stretch, of the belt G, and the cam P and the said gear K are so timed in their movements that they will overcome the variation in the distance between centers of the gears F and H, due to the up and down movements of the former, and hence it will be seen that the relative position of the links 1 and 14 of the sprocketbelt G will not vary at any time during the up and down movements of the rail A and the shafts B and C. From this it follows that the speed of the shafts B and C will be the same at all times, and hence there will be no liability of backlash or the production of an uneven twist to the yarn.

In the practical operation of our improvements the cam P rotates in the direction indicated by arrow until the antifriction-roller R, against which the cam acts, and the re ulator-sprocket gearK reach the highest point of their traverse, when the cam reverses and moves in the direction opposite to that indicated by arrow, andthe regulator-sprocket gear K moves downward synchronously with the bobbin-shaftsB and C.

It will be gathered from the foregoing that notwithstanding the important purpose served by our improvements the same are simple and inexpensive in construction and do not materially increase the cost of manufacturing and operating the slubber or flyframe.

We claim 1. In .a slubber or fiy-frame, the combination of a driving sprocketgear, a vertically movablebobbin-shaft, a sprocket-gear fixed to and movable vertically with the'bobbinshaft, a sprocket-belt connectingthe sprocketgears, a regulator-sprocket gear engaging. onestretch of the sprocketebelt and movable up and down synchronouslywith the bobbinshaft, and means formoving thesaid regulator-sprocket gear up.

2. In a, slubber 0r fiy frame, the combination of a, driving-wheel, a vertically-movable bobbin-shaft, a Wheel fixed to and movable. verticallywith the bobbin-shaft, a belt connecting said wheels, aregulator-wheel engag:

ing one stretch of the belt and movable up and down synchronously with the bobbinshaft and means for moving said regulating- 4 wheel up.

3. In a slubber or fly-frame, the combination of a driving s rocket-gear, a verticallymovable bobbin-s aft bearin a sprocketgear, a sprocket-belt arrange on and connecting the said gears, a vertically-movable slide carrying an antifriction-roller, a guide Way for said slide, a cam movable first 1n one direction and then in the other, and arranged in engagement with the antifriction-roller of the slide, a shaft through which the cam is so moved and a regulator-sprocket gear carried by the slide and engaging one stretch of the sprocket-belt.

In testimony whereofwe have hereunto set our hands in presence of two subscribing witnesses. v
